Jacob Junyi Chen

😍 Research Interest

My research focuses on exploring and developing scalable, multi-modal world models. By building foundational systems capable of concurrently processing, understanding, and generating diverse data modalities—including text, images, videos, and 3D representations —I aim to achieve a universal, comprehensive understanding of our physical world.
